“…Hirotani and Nakatani (1987) report that free-living Japanese wild boar dams (Sus scrofa leucomystax) drive their offspring away one month before farrowing, something not observed in this study. In accordance with earlier findings (Teillaud, 1986) the agonistic interactions decreased one week after farrowing, which was followed by the sociality phase.…”

“…edges to marsh land (Dardaillon, 1986) or dense forests and often in slopes facing the south, south west and east (Janeau and Spitz, 1984). After parturition, the sow stays in the nest for up to 2 weeks before joining the family group again, in which the young are reared communally in nursing groups consisting of 2 or more sows with piglets of about the same age (Gundlach, 1968;Delcroix et al, 1985;Teillaud, 1986;Dardaillon, 1988).…”

“…an increased aggression (Gundlach, 1968;Martys, 1982;Hirotani and Nakatani, 1987) and an increased activity before farrowing (Eguchi et al, 1998), and a decrease in agonistic behaviours after farrowing (Teillaud, 1986). Moreover, the activity decreases in wild boar sows with young piglets (Cousse and Janeau, 1992) and they tend to prefer protective and dense habitats (Spitz and Janeau, 1995;Fernández-Llario et al, 1996).…”

Behaviour of European wild boar (Sus scrofa) in connection with farrowing in an enclosure

et al. 2011

Wild boars (Sus scrofa) are often kept in enclosures for hunting or meat production purposes in Sweden. The sows are known to undergo behavioural changes in connection with farrowing and their natural behaviours may be compromised by the limited area of the enclosure. The aim of this study was to quantitatively describe wild boar sows' behaviour when farrowing in an enclosure. A field study was carried out in a hunting enclosure, where 1200 hours of behavioural recordings and data from 22 farrowings were collected. According to the results, the farrowing period could be divided into 3 phases: pre-farrowing, isolation and sociality phases (in relation to farrowing: day -14 to -1, day 1 to 8, day 9 to 14 respectively). The activity decreased during isolation and increased in the sociality phase (p<0.05), whereas the average distance to other individuals increased during isolation and decreased in the sociality phase (p<0.05). Nose contacts with other individuals increased in the isolation phase (p<0.05) and habitat use changed towards more protective habitats after farrowing. 68 % of the nests were situated in edges between 2 habitats of different vegetation density and 73% had some kind of protection to the north. We conclude that farrowing induces a number of changes in the activity, social behaviour and habitat preference in captive European wild boars. This may need attention when enclosures for this species are designed.

“…After the isolation phase the family groups join in nursing groups consisting of two or more sows with piglets of about the same age. By then, agonistic behaviours have normally decreased (Dardaillon, 1988;Delcroix et al, 1985;Teillaud, 1986). When domestic pigs are kept in enclosures outdoors, they show more or less the same overall pattern in their maternal behaviour (Jensen, 1986;Jensen et al, 1987).…”

Extensive infanticide in enclosed European wild boars (Sus scrofa)

Infanticidal behaviour, behaviour with wide welfare implications, is wide-spread among animals of various taxonomic groups, but has not previously been systematically studied in European wild boars, which are commonly kept in enclosures in Sweden and Finland for meat and recreation hunting. We studied the behaviour of wild boars in one enclosure during three reproductive seasons. Non-maternal infanticide was documented in 14 out of 22 litters, causing the deaths of all piglets in all but one affected litters. Infanticide was typically performed during or shortly after parturition by a sow which was older (P<0.05) and tended to be larger (P=0.068) than the victimised sow, and was not affected by whether or not the involved females were mother-daughter pairs. A questionnaire sent to 112 owners of a total of 116 enclosures in Sweden and Finland resulted in 62 valid responses. Non-maternal infanticide was reported to be the most common cause of piglet pre-weaning mortality, which in total (including all causes) was estimated to be 29.1 %.The occurrence of infanticide was unrelated to size of enclosure (less or more than 20 ha) and to variations in supplementary feeding routines (less or more than once a week) (P>0.05), which may suggest that the behaviour could be a part of the normal behavioural repertoire in European wild boars. The observed levels of infanticide constitute a major welfare problem in captive wild boars.3
